深孔预裂爆破过地质构造技术在阳煤一矿的试验应用

Experimental Application of Deep Hole Pre Splitting Blasting Crossing Geologic Structure Technology in the No.1 Mine of Yangquan Coal Mine

本文介绍了深孔预裂爆破过地质构造技术在阳煤一矿81402工作面的试验应用,通过合理确定钻眼布置参数,深孔预裂爆破技术可使致密坚硬的构造岩石形成多条裂缝和破碎带,降低了采煤机的截割强度,提高了割岩速度,大大提高了过构造生产效率和过构造安全性,对阳泉矿区回采过构造技术的发展具有积极的借鉴和推广意义。

This paper introduces the test applications if the technology of deep hole pre splitting blasting in geological structure in 81402 working face of Yangquan Mine. By means of the reasonable hole arrangement parameters, deep hole pre splitting blasting technology can make dense hard rock formation of multiple cracks and fracture zone, reducing the cutting strength of the shearer, improving the speed cutting rock, greatly improving the construction effciency and structure security, which has a positive reference and popularization signifcance to the development of construction technology for the mining in Yangquan mining area.
